reducing the eflieiency of the lock and lx' consequent liability of the accidentel dieplncernent of the earringe, due to the vilhrntinn set np when operating themnchine, for instance.

'In the present invention, the tnbnlating her is mounted on 'the eerrmgeland carries one er more stops thereon, which coact with stationary abutment. A l One of the oliijecte of the invention is to provide an improved end simple Lineens to enebif, the carriage td be edjustel` to end hei i `fir'l'nly in 'any position intermediate the `poin s at which the tabnleting stops are set,

To thesefand other ends, therefore, my vinvention includes certain novel features and combinations of parts, all of which will be more fully set forth hereinafter and particularly pointed out in theclains lIn the drawings, Figure 1 is .a rear view. of oneend of a traveling carriage, of the well known virales` calculating machine, equipped with one embodiment ofthe invention' v Fig. 2 is a cross sectional view through the carriage, showing, a tabulating stop 'in'effective position, the minutely adjustable column spacing mechanism being idle;

A carriage support or casting 206i (Fig. 2), secured by bolts 1155 to the side frames 967 of a. Wales calculating machine, is' provided with ways 2067*, between which travels theslide 2065 forming part of the carriage. Rollers 1191 interposed between the-adjacent edges of the slide and the ways, respectively, enable the slide to be readily shifted along the ways.

An axle 2004, (Figs. 1 and 2), joiirnaled in end plates 2010 secured to the opposite ends of the slide, supports ,the usual platen 2094, equipped with the custoinarjY line space ratchet 2020, a line space detent stary wheel 1117 being fixed to turn with the axle.

Suitable pressure rolls 2007 and 2007 (Fig. 2)., Contact the platen to hold the 'paper thereagainst and enable it to be fed step by ste as the platen is turned.

Tihe foregoing is not claimed in this application, and forms a part ot the invention -only in so far as it is combined with the novel features hereinafter set forth.

lrThe traveling carriage permits the respective columns on theI work sheet inserted around the platen, tobe brou'ght to the printing point, to -enableainoimts tobe listed in parallel columns. y

Tabulating mechanism to arrest and hold the carriage'. when the desired column hasl been brougbtfto the printing point, coin-l prses 1a tabulating bar 2092 1/-1 (Figs. 1, 2

and 3) toothed along its upper-edge.

ment 2091 1/2 secured to 'a vfixed part of the" machine, as the carriage way 2067 a, to arrest the carriage where adjusted. These stops, of which one or more maybe used, each comprise a yoke loosely embracing the tabulating bar 2092 1/4 from beneath, the

upper end of ythe yoke being closed by a toothed block 2092 1/2, Whose teeth are' adapted `to mesh with the teeth on'the tabulating bar to secure the stop to the bar. A

spring 2080, one end of which encircles and is held in place by a coibined spring retainer and stop 2055 wardly between the arms o'f the yoke, resses against a guard plate 2021 1/,4 loose y-held between the arms of the yoke, and in sliding contact with the smooth lower edge of the tabulating bar, to releasably maintain the aan ofthe block 2092 1/2 in mesh with the. teeth of the tabulating bar.

projecting 'up-I A tooth or stop 2018 1/4 projecting fromy the inner arm of the tabulating yoke, seats in a vertical recess 2091 1/2 formed inthe abutment 2091 1/2, to lock.the carriage where adjusted, the stop tooth being held in its seat b v a restorin spring 1185, (Fig. 1), one end of which is xed to a stud 2051 1/8 projecting from one of the gudgeonsv2093, the opposite end of the spring being connected to a. post 2058 1/2 secured to a part of the carriage slide 2065.

A finger lever 2022 1/2 fastened by af hub 2031 to the projecting end of one of the geons 2093, extends upwardlyto a position convenient to the operator, the lever being slotted, as at 2022 1/2, (Fig. 2) to embrace the platen axle 2004. which serves as a stop to arrest the throw of the level' ineither dpirection. Rocking the lever rearwardlyrocks the tabulating bar against the tension of the restoring spring 1185, to disengagethe active stop 2018 1/-1 from the abutment 20 9 1,1/2

gud-

to enable the carriage to be shifted iii either direct-ion Vto bring the desired column to the printing point. Releasing the lever, frees the tabulating b'ar 'to the action of its restoring spring 1185. and as soon as the carriage in its travel. brings the next jstop to registry with the abutment, the spring snaps the stop into engagement therewith to lock the carriage where adjusted. Should ay stop have been set to arrest the carriage in any columnivhich it is desired to skip, the operator merely continues to hold the leifer in operated position while the carriage is ,shift- -ed until Vsuch, column has passed the printing point, after which the lever may leased.

The opposite ends of the abutmentare reversely inclined tof enable the `tooth 2018 1/1a i of the stop, 'when the carriage is shifted in eitherdirection, tov ride up the adjacent.

incline 'untill it registers with the recess i 2091 l/2a in which it is seated by the spring One of the important advantages of this tabulating mechanism, resides in the ease with which the adj ustnients are made for arresting the carriage atvarious points in its travel. Assume that-the carriage is at its right hand limit of travel, where it is locked i by the stop 2018 1/4 at the left hand end of the. tabulating bar.

The operator, after inserting the columnruled worksheet around the platen, while maintaining his position in front of the niachine, and without touching the release lever 2022 1/2, 4reaches behind the carriage and pressesupwardly on the active stop. The ower end ofthe stop carries oppositely extending inclined lips 2018 1/4 to 'forni 'a inger rest. Pressing upwardly on the stop shifts it l,transversely ofthe bar 2092 'v1/4, compressing4 the spring 2080 until the spring Vplate202l 1/4, which contacts the tabulatlng'bar at all times, and arrests further ltravel Aof the stop. 4The arms of the yoke slide relatively to the' guard plate, and lift the toothedblock 2092 1/2` out of mesh with the tabulating bar ,2.092 l/l', thus disenga'g ing ythe tabulating bar' and stoplp'reparat'ory Vto a. relative `adjustment thereof.

' The distance through which the stop can beshifted transversely of the bar is 'not sufficient to disengage the stop tooth 2018 41/4* from its seat 2091 l/2l 1n the abutment 2091,1/2, the effective area of which -is large enough to vmaintain engagement with the sto tooth throughout its transverse travel.

he operator, while holding the stop 2018 1/4V disengaged, with his other hand merelyV Slides the carriage until-the desired column is `brought to printing position, whereupon he frees the stop to the action of its sprlng 2080, which immediately rengages thetoothed block 2092 1/2" with A,the toothed tabulatingbar 2092 .1/4.. The release lever 2022 .1/2.`is now o erated to disengage the-tabulating sto rom the abut-l ment, the carriage slid enclivise lto brin the next column to thev rioting point, the ever 2022 1/2' being fr ee as soon as the adj usted stop 2018 1/,4 has passed 4out of registry l `with the abutment, and the foregoing procedre repeatedf to adj ustthe second Stop for the second column. 1 It Will'be seen that the carriagel and tabulating bar are adjusted relatively to the stop instead ofthe stop 'being adjusted along the ta'bulating bar as is usual, and that the preferred 'adjustment is readily accomplished, no Wrenches'or other `tools being required, nor is it necessaryfor the operator to move retainer. postr 2055y 1/4 strikes the guard.

from in frontof theymachine. The tabulating stop maintains its enga ement with the abutment throughout the a justment of the carriage for any particular column, and the necessity for try oui s or preliminary adjust-- ments'of the lstops is reduced to a minimum, the operator being able. to quickly detre mine the exact ptint at which the stop should be locked to :he tabulating bar to a rto be locked with the desired Columns at the printing point, witlout changing the tabu.- lating stops adjusterf for the more commonly used form, I provide what I'terin a minuti-ily adjustable space bar mechanisroR whereby the carriage can be locked 'at any desired point in Vits travel u ith a greater degree of v accuracy-and finer a ljustment than is possi ble with the tabulati ig'mechanisrn above described, enabling ihe operator to print amounts in the exaitplace. in the column, where they should a ppear.

Friction locks `for this purpose have hitherto been employed, but my invention provides a simple'and more efficient means for this purpose.A t In my invention, Ihe minutely adjustable 4space bar 2092 1/8 (Figs. 1, 2 and 3),' preferably travels with the carriage, it being conveniently supported by the lower ends of depending arms 202;| 1/2 secured by screws 2060 (Figs. 1 and 6` to the tabulating har 2092 1/4. The mini te space bar thus parof the tabulating ba j A dog or 100k 2025 1/4 pivoted 2050.7/8 t0 a bracket '2025 faster ed to a stationary part of the machine, as thi i lower carriage way or rai12067,has a tooth ed j aw 2025 1/4"L turned upwardly to lie opposite the outer edge ot'` the minute space bar, which is preferably serrated,as at 2092 1/8. r

A spring 2080 1/8 iormally holds the dog in idle position.

An operatin leve. 2025 '1/8 (F igs.l 1, 4 andf), pivote at- 2)50 1/8 to the 4bracket 2025, carries a. follow'i er, as a roll2046 1/4 intermediate its ends. The follower normallyrests in a recess 2025 L/4" 'formed at one end of av ca m face2025-I/4,c formedalong one n using this mi vice, the operator, aft ar inserting thejspecial form in the machine, merely reaches behind nu ze, column spacing deshe carria e and throws the operating lever 2025 1/8 rom the idle position shown in Fig. 4 to the active position vshown in Fig. 5,

to cause the follower 2046 1/4. to ride up the cam or inclined face 2025 1/4" 2025 1/4 until it seats in a terminal recess 2025 1/4", and locks the dog in eli'ective position against-the tension of spring 2080 1/8. The follower, us it rides up the inclined face, first forces the dog inwardly to bring its toothed jaw 2025 l/4n against the outer serrated edge of the minute space bar 2092 1/8, and then4 rocks the latter inwardly.

The tabulating bal: 2092 1/4 with its stop 2018 1/4, because of 4its connection with the minute spacebar, through the arms 2025 1/2, is thereby rocked outwardly against thc tension of lthe. restoring spring 1185 to disen-r gage the sto from its abutment 2091 1/.2 and thus disa le the-tabulating mechanism.

The carriage is locked against shifting soon as theserrations of the dog mesh fairly with those on the minute space bar, and prior to the disengagement of the stop from its abutment. i

The releasin lever 2022 1/2, being -fixed to the tabulatingar, rocks therewith when the bar 2092 1/4 is shifted outwardly by the pressure of the d og 2025 1/4 againstv the minute s ace bar 2092 1/8, but the effective throw o the dog is arrested by the contact of thel edQe 2025 ,Il/4*" of the dog with the bracket 2 I (Fig. 45) before the :forward end of the slot 2022 1/2'.a of' the' lever 2022 1/2 contacts the laten axle .2004, Vwhich axle positively limlts the distance through which thev tabulating mechanism can 'be rocked. Thus the minute space bar is capable of an `additional inward movement, suilicient to disengage itself from the dog after the dog has reached the Iend of its eiective throw. This arrangement permits the operator to release Vthe minute space bar from the dog -While the latter is inactive position, b

rocking the release lever 2022 1/2 to the limit of its rearward stroke, to enable the carriage to be vadj usted in either direction to bring.-

the' desiredspecial column to theprintin point, .after whichl the lever-is released an the restoring .spring 11.85 returns the minute space bar into mesh with the dog. The fine serrationsm'ord the possibility of ver accurate adjustments of the carriage column ruled -forms relatively Vto the printin l oint;

By s i ting the (pe'rating 1ever2025 1/8 in the opposite rection, the -:follower 204e1-/4-.ridesdown the'raeline 2025 l/fe,4

freeing the dogto the action of its releasing spring 2080 1/8-, which returns the dogA to idle position, `thus. disabling the minutely adjustablesiace bar mechanlsin and releasing thetabu ating mechanism to theaction of its restoring spring 1185, which immediately rocks the tabulating bar and its stop of the dog` to force the dog aainst them'i-nute sp ulatirg mechanism. and a j.

back to efective position relatively t'o the abutment 2091 1/2. y

Obviously, the positions of the minute space bar. and its locking mechanism might be reversed relatively to 'the carriage and machine, without sacrificing any 'of the advantages of the structure as herein set forth.
